The current sounds and animation for ships warping into/out of a battle are good, but I would like to suggest a way to improve them.

When watching shows (Star Trek, Star Wars) or playing other games (EVE Online, Mass Effect, HALO, Elite: Dangerous) there is a very heavy weight that comes with new ships entering a system.

Each version does it a little differently, to their own respects. But, every ship has a "thump" as it enters the system. This adds a "weight" to the ships. Letting you know it's here for a reason and a purpose, usually to do damage. It also sets the tone for the upcoming conflict that usually follows.

Sometimes, it's followed by more sounds or animations as a by-product of the slip-space jump. This can range from thunder, cracks, the sound of steel bending (as the ship adjusts to it's new atmosphere conditions), to many other things.
